  • Patent number: 7522030
    Abstract: A starter relay comprises a container composed of an electrical insulating hard resin, a resistor having a positive resistance temperature coefficient and housed in the container, and contact springs of feeding devices having conduction and resilience configured to press the resistor to establish connection with the resistor. The contact springs each include a body, two arms extending from the body, and spaced press-fit contacts extending from the arms to press the resistor. The press-fit contacts of one of the contact springs and the press-fit contacts of the other are arranged in crossed directions. Thus, a broken fragment of the resistor is not pinched between the contact springs even when the resistor pinched is broken.

  • Patent number: 7417201
    Abstract: Future motor vehicles will require additional lighting means. Additional lighting means are required, above all, in conjunction with environmental sensors, especially sensors which are used in night vision systems. As a result of the generally increasing number of electric and electronic systems in motor vehicles, such systems must be easy to operate for the driver. The invention thus relates to a switching arrangement which enables a plurality of lighting systems to be ergonomically operated on one motor vehicle. Said switching arrangement comprises a single switch having a plurality of switching stages. In this way, all switching stages pertaining to different lighting systems are located in the same switching region, enabling the lighting systems to be operated in a simple and intuitive manner.

  • Patent number: 7408437
    Abstract: An object of the invention is to provide a resistor element that makes it possible to adjust the resistance value of a precursor easily in producing a resistance element having a target resistance value from the precursor, as well as to the precursor and a related resistance value adjusting method. A precursor 70 has a meandering resistance pattern formed on a front surface 11 of a substrate 10 as well as at least three trimming lines. The precursor 70 is configured so as to be defined by a geometric sequence that satisfies Inequality 0.5?k<?k+1<?k, where ?k is the general term of the sequence that is obtained by arranging, in descending order, resistance value increases of the precursor at the time of cutting of the respective trimming lines and normalizing the thus-arranged resistance value increases by an initial resistance value of the precursor in a state that none of the trimming lines are cut.

  • Patent number: 7405373
    Abstract: The switch structure according to the present invention is obtained by interposing an elastic connection member between the circuit board provided with electrodes and a push switch fixed to a case of an electronic device. The elastic connection member has a structure in which conductive layers and insulation layers are alternately laminated. The conductive layers of a first lamination layer surface on which the conductive layers and the insulation layers of the elastic connection member are exposed abut against the electrodes so that the electric connections therebetween are established. The push switch is pushed down, and a contact portion thereof abuts against the plurality of conductive layers on a second lamination layer surface, whereby the electrodes are in a conductive state. Even if the push switch is pushed strongly, the elastic connection member deforms to absorb the force. As a result, the switch structure which hardly breaks is obtained.
